** Description changed:
- The prompt setting in /etc/update-manager/release-upgrades controls
- whether the user is prompted to upgrade, but also controls whether the
- user can manually upgrade using do-release-upgrade -d.
+ Impact
+ ------
+ If Prompt=never in /etc/update-manager/release-upgrades and
do-release-upgrade is run a likely confusing message regarding no new release
being found is returned. This is can be a lie and doesn't help people upgrade
if there is in fact a new release.
+
+ Test Case
+ ---------
+ 1) set Prompt=never in /etc/update-manager/release-upgrades
+ 2) run 'do-release-upgrade' on 18.04 and also run 'do-release-upgrade -d' on
18.10
+
+ Observe an error message regarding no new release being available or for
+ the -d case on 18.10 one regarding upgrades to the dev release only
+ being supported from the latest supported release.
+
+ With versions of update-manager and ubuntu-release-upgrader (which
+ depends on the changes in update-manager) from -proposed you will
+ instead see a message about prompt being set to never and the file to
+ modify so you can upgrade.
+
+ Additionally, release-upgrades has been modified to indicate that use
+ never won't allow you to upgrade and to clarify what happens if you've
+ set lts on a non-lts release.
+
+ Original Description
+ --------------------
+ The prompt setting in /etc/update-manager/release-upgrades controls whether
the user is prompted to upgrade, but also controls whether the user can
manually upgrade using do-release-upgrade -d.
Steps to reproduce:
1) On an 18.04 machine, set Prompt in /etc/update-manager/release-upgrades to
lts or never.
- 2) Attempt to upgrade to 18.10 beta using do-release-upgrade -d.
+ 2) Attempt to upgrade to 18.10 beta using do-release-upgrade -d.
3) The upgrade reports "Upgrades to the development release are only
available from the latest supported release." This is both an incorrect error
message, and it prevents upgrade even though the user has specifically
requested the development version.
Possible fixes:
1) The documentation should be changed to indicate that the Prompt argument
controls both whether you are prompted to upgrade, but also whether you can use
the upgrade tool at all.
2) A second configuration option should be added to allow the admin to
control the prompting for upgrade separately from the ability to upgrade,
allowing users to upgrade the system manually, even when Prompt is set to never.
Question: Is the default setting of Prompt=lts going to prevent users
from upgrading their 18.04 machines to 18.10 until they change it to
normal?
